Harry Kane came back to chase Tottenham in his second outing against his old club.
But the Spurs icon remained the red face after the balloon of a penalty over the bar.
The captain of England faced Spurs for the second time since he came to Bayern Munich in 2023 for £ 86 million.
And again, it was a friendly, Spurs' last game for the UEFA Super Cup collision next week with Paris Saint-Germain,
He showed the kind of clinical finish that helped him to become the record goalscorer of North Londoners with 280 strikes with his 12th minute more open.
But shortly thereafter he repeated the terrible Spot kick that he hit three years ago for his country in the quarterfinals of the World Cup by shooting in Row Z..
However, Bayern did not stop running up because they added three stunning further goals from Kingsley Coman, Lennart Karl and Jonah Kusi-Asare.
It was a difficult afternoon for Thomas Frank, who gained a painful insight into the quality of the opposition with which his injury side can be confronted in the Champions League this year.
Spurs were without starters from the first team James Maddison, who will miss the rest of the season with a torn front cruciate ligament, Dejan Kulusevski, Destiny Udogie and Dominic Solanke.
While the loyal son Heung-Min, old mucker from Kane, is no longer in the club after his blockbuster relocation to Lafc in America.
Spurs gave Joao Palhinha his debut only a few days after completing his loan movement – from Bayern.
The Portuguese, 30, has a shortage of fitness, but received a thorough training in the 45 minutes that he played against his parent club, whose attacking players caused all kinds of problems.
Bayern's two balloon d'Or nominees, Kane and Michael Olise, combined for the opener in the 12th minute.
Olise held a ball from deep to Kane, which controlled it beautifully before he shot clinically in the far corner with his weaker left foot.
The three Lions captain had watched a fraction offside in the structure, but the goal was given anyway. He didn't celebrate it, out of respect for his old side.
Minutes later Kane was given the chance to bring the score to 2-0 from the penalty place after Palhinha Josip Stanisic had hit the box, although it was doubtful how much contact was made.
Everyone in the Allianz expected that it would just bulge and that Kane would have his second against the club that made him.
But instead, the 32-year-old slipped in his run-up and skied him far beyond the bar, just as he had done in Qatar three years ago.
However, this was clearly a much less serious occasion and Kane, together with his Bayern teammates, quickly removed the blunder.
It was one -way traffic from them until the break.
“But it is remarkable that Bayern did not add to their lead, despite a flurry of opportunities that their way took.
Midfielder Leon Goret2zka was very wasting.
Traces, meanwhile. Leek a shortage of creativity without the wounded Maddison.
Frank already wanted to sign a new no.10 before the English star did his ACL against Newcastle.
This weak display only emphasized the need for more help in the transfer market, in which Bayern shoots three bangers home, thanks to Coman Plus Teenage Hubs Karl and Kusi-Asare.
Spurs -fans will undoubtedly fear the worst when they are confronted with PSG, the reigning Champions League winners, in the Super Cup next Wednesday.
